The 4/4 is now dormant and I suspect it’s reintroduction will depend on how well the Plus4 sells and whether the pricing differential will warrant a lower powered entry model on the new chassis
The Plus Four at 255bhp and £65k is a very appealing proposition. If they were to do a 170bhp 4/4 at £55k it would also be mightily appealing, but would it be achievable? There's be little point producing a new 4/4 if they couldn't get the cost down significantly over the Plus Four. Who would go for it?
